Shuttle Suit Mockup

The visitor center featured a number of space suits in the auditorium,
including a Shuttle Extravehicular Mobility Unit (EMU) mockup.

Unlike previous American space suits, the Shuttle EMU is not a single garment.
There are various components of the base suit, including arms and upper and
lower torso assemblies, in addition to the traditionally-removable gloves and
helmet. These additional components are mixed and matched to fit the astronaut
performing the EVA.

As such, there are only a very small number of "suits", and they are still in
use on the ISS. Most or all "Shuttle space suits" displayed in museums are
mockups.
